`IMPRGVIENIENT IN STEAM WATER-ELEVATORS.

To all whom it may concern: v

Be it known that I, WILLIAM BURDON, of Brooklyn, in the county of Kingsand State of New York, have invented 4a new and useful Improvement-inApparatus for Raising and Forciu g Water by the Condensation andPressure of Steam; and I hereby declare that the pheric pressure isafterward expelled by the pressure of steam, which is subsequentlycondensed to `form a vacuum for the repetition of the operation. Theimprovement consists in the combination, with the two chambers of theapparatus, of piston water-rams, having attached to their pistons valveswhich control the escape of steam from the chambers to act upon pistonsor their equivalents for the pur-` pose ofmoving the steam-valve orvalves to vadmit and shut oft' steam to and from each chamber in turn. t

The accompanying drawing represents a central vertical section of anapparatus constructed according to my invention. i

A A are the main water-chambers of the apy paratus,`which are arrangedside by side or in any other suitable manner, and may be of any formdesired. Each communicates, through a valve, B, with 'a suction-pipe, C,and is provided, for the attachment of a discharge-pipe, with a socket,D,`furnished with a valve, E.

` F is the main steam-valve, which is of hollow cylindrical form withclosed ends, and is provided with two ports, one, c, inits upper side,

y and the other, b, in its lower. The valve-box G, within which itworks, is of corresponding form, and horizontally arranged. The box isconnected with a steam-generator by a pipe, H, which communicates withthe port a in the upper side of the valve, and it has formed in themiddle of its lower side two ports, c c,

' which lead through pipes e e into the chambers A A, and with which theport b in the valveF 133,753,l dated December 10, 1572;A antedatedDecember 4,1572.

alternately communicates, and so admits steam to either chamber andshuts it off from the other. VFrom each end portion of the valveboxthere extends into its adjacent chamber A a pipe, I, and between thispipe and the valve there is arranged, in the valve-box, a loose piston,J. Under its pipe I there is secured in the bottom of each chamber thecylinder K of a hydraulic ram, the piston L of which hasattached to itav rod, M, furnished at its upper end with a sleeve-like valve, N,which, in the operation of thepiston, slides on the lower part of thepipe I, and so covers and uncovers ports or holes f therein, -and sogoverns the admission of steam from the chamber to the valve-box toshift the valve. The cylinder K of each chamber A communicates at thebottom through a pipe, 0, with the lower part of the other chamber, andsaid pipe is provided with a cook, g. The chambers are provided withcondensing-pipes P P, each of which communicates between the lower partof one chamber andthe upper part of the other.

To start the apparatus, the chambers A A are first iilled with watereither by pouring it in through openings which are afterward closed orby shifting the valve and so admitting steam to .both chambers andallowing it to condense willbe raised by atmospheric pressure. lling thechambers the pistons L L of the rams are raised. The valve is thenshifted to admit steam to one of the chambers, which, for convenience, Iwill suppose to be the left, where, acting on the water, it expels it,and at the same time slowly forces down the piston L of its cylinder K,and so opens its valveN and allows steam to escape from the said chamberup its pipe I into the left-hand end of the valvebox to act upon theleft-hand piston for the purpose of pushing it and the valve F to theright, and thereby shutting oil' steam from the said chamber andadmitting it to the right one, which then commences discharging. Thecock g on the pipe O is so adjusted that the lowering of the piston andconsequent Openingof the valve N takes place at or near the completionof the discharge of the chamber.

right to the left chamber through the proper condensing-pipe P andcondenses the steam in the latter, thereby termin g a vacuum therein s0that it lls while the right one is dischargin g. While the right chamberdischarges some water is forced therefrom through its connected pipe Oagainst the bottom of the piston of the ram belonging to the leftchamber, and the said piston is thereby slowly raised so that itsattached valve N is made to close the ports or holes f in the pipe I, onwhich it works, while the piston of the right-hand ram is forced down bythe pressure above it,- and so made to open its attached valve Naudadmit steam to the right-hand end of the valve-box G to act upon theright-hand piston and move the valve F to the left, whereby the supplyof steam is shut off from the right chamber and again admitted to theleft. The discharge of therightchamberhavingbeencompleted about the timethe valve is reversed condensation then takes place and forms a vacuuminto with the discharging and lling of the other, the valves N N beingeach operated upon in turn at the proper time by its respectiverampiston L to allow the escape of steam from its respective chambcrforthe purpose of operating the steam-valve F.

I do not coniine myself to the particular kind of main valve employed toadmit and shut on' the steam to and from the chambers, nor to theparticular kind of valve used to control the escape of steam from thechamber to operate the first-named valve; but

What I claim as my invention is- The combination, with each chamber ofthe apparatus and with the valve for controlling the escape of steamfrom the chamber to operate the main valve, of a piston Water-ram, opento its own chamber and communicating by a pipe or contracted openingwith the other chamber, for operation substantially as herein set forth.
